The water mill is a machine to convert energy from water that flows or falls into a useful form of energy, such as Micro-Hydro Power Plant. In the middle Ages, the mill ordinary water is used as a tool to move the factory etc..

A water mill usually consists of a wooden or metal wheel, with the number of blades / blade or bucket that is placed on the outer edge of the surface / wheel around wheel. Generally, wheels mounted vertically on a horizontal axis, the windmill with a vertical shaft, the bowls or Norse wheel mounted horizontally on the horizontal. Vertical wheel can generate power / energy from the axle directly or through a gear chain (chain & sprockets), belt / belts, or gears. On a horizontal mill, the load, usually worn on the vertical axis.

Undershot wheel (also called flow wheel) is a vertical mill wheel, the wheel turned by water flow that drives impeller blades, blade at the bottom of the wheel. Undershot the name comes from "hitting bottom" wheels. This type of waterwheel is the oldest type of windmill. It is also regarded as the most efficient type, subtype waterwheel this example Penciled Windmill, Windmill and Windmill Sagebien Zuppinger, and has a rather greater efficiency than the traditional undershot wheel. The advantage is cheap, simple, and easy to build it and also not impact on the environment due to virtually no change in river flow. The disadvantages are low efficiency, meaning both are used only where the water flow rate quite hard to give a better torque. High water falls (head) is not useful for the undershot wheel. Only the best for shallow water pumping.

Undershot wheel is also suitable for use on the installation of a floating platform (pontoon). Initially, the Roman general Belisarius (probably) built during the siege of Rome in 537. Then the wheel is sometimes installed in the downstream of the bridge where the bridge poles can increase the flow velocity.
